This is a Devise extension to add Two-Factor Authentication with Authy to your rails application.

Get an Authy API Key: https://www.authy.com/signup

See https://github.com/authy/authy-devise/tree/master/authy-devise-demo

First create an initializer in config/initializer/authy.rb

Authy.api_key = ENV['AUTHY_API_KEY'] || 'your_authy_api_key'
Authy.api_uri = 'https://api.authy.com/'

You can get the AUTHY_API_KEY at https://www.authy.com/signup

Next add the gem to your Gemfile:

gem 'devise'
gem 'devise-authy'

And then run bundle install

Add Devise Authy to your App:

rails g devise_authy:install

--haml: Generate the views in Haml
--sass: Generate the stylesheets in Sass

Configure your Devise user model:

rails g devise_authy [MODEL_NAME]

or add the following line to your User model

devise :authy_authenticatable, :database_authenticatable

Change the default routes to point to something sane like:

devise_for :users, :path_names => {
	:verify_authy => "/verify-token",
	:enable_authy => "/enable-two-factor",
	:verify_authy_installation => "/verify-installation"
}

Then run the migrations:

rake db:migrate

Now whenever a user wants to enable two-factor authentication he can go to:

http://your-app/users/enable-two-factor

And when the user log's in he will be redirected to:

http://your-app/users/verify-token

If you want to customise your views, you can modify the files that are located at:

app/views/devise/devise_authy/enable_authy.html.erb
app/views/devise/devise_authy/verify_authy.html.erb
app/views/devise/devise_authy/verify_authy_installation.html.erb

If you want to customise the redirects you can override them within your own controller like this:

class MyCustomModule::DeviseAuthyController < Devise::DeviseAuthyController

  protected
    def after_authy_enabled_path_for(resource)
      my_own_path
    end

    def after_authy_verified_path_for(resource)
      my_own_path
    end

    def invalid_resource_path
      my_own_path
    end
end

The install generator also copy a Devise Authy i18n file which you can find at:

config/locales/devise.authy.en.yml
